Kokubun Temple
The system of regional provincial temples everywhere in Japan (国分寺 Kokubun-ji for monks; 国分尼寺 Kokubun-niji for nuns) had been stablished by Emperor Shomu (Shoomu Tennoo (聖武天皇 Shōmu Tennō) (701 – June 4, 756) ).
He had the temple Todai-Ji (Toodaiji 東大寺) the "Great Eastern Temple" erected in Nara and the Great Buddha Hall (Daibutsuden) is the largest wooden building in the precincts of this central Kokubun-Ji.

The temple Hokke-Ji (法華寺 was the temple for nuns in Yamato/Nara.
It was built by the Emperess Komyo (Koomyoo (光明皇后, Kōmyō kōgō) (701-760) in 745).

Kokubun-ji (国分寺) were Buddhist temples established in each of the provinces of Japan by the Emperor Shōmu during the Nara period (710 – 794). Shōmu (701 – 756) decreed both a kokubunji to be established in each province for monks and a 国分尼寺 (kokubunniji) established for nuns. Tōdai-ji, the provincial temple of Yamato Province, served as the head of all kokubunji, and Hokke-ji held that duty for the kokubunniji.
The words "kokubunji" and "kokubunniji" gave rise to many place names still in use today, including:
Kokubunji, Kagawa
Kokubunji, Tokyo
Kokubunji, Tochigi- quote wikipedia -
